= nnpllcatlcnfllcd Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Lubricator- Bearings, of which the following is a specification.

My invention relates to improvements in lubricator bearings for use in connection .1 with vehicles, machlnery, etc., where it is de- 1 sired to lubricate the bearings such as sprin and shackle bolts, used in connection witi "autemobiles or similar vehicles, or the axle or spindle bearings of wheels, and" other by the application of oil or moving parts,

ose of preventing fricgrease for the pur tion, wear, and the ike.

The present embodiment is In the form of a spring or shackle bolt frequently. used in forming the hearing or connection between the springs and t e side bars or mem bers of automobile vehicle frames. The primary object of the invention isto provide a generally improved lubricat'or bearing of this class, of exceedingly simple, cheap, and efficient construction, .and par; ticularly to eliminate the usual separately formed and attached grease-cup by the provision of a lubricant orgrease-contaimng chamber or receptacle within the bearing member or bolt, together with. novel mecha nism for feeding the lubricant from the lubricant or grease-containing receptacle or chamber to the friction bearing portions or surfaces of the hearing, as desired.

A still further object is to improve the construction and arrangement of the headcap or closure for the lubricant or greaseand' the means for attaching said hea -cap'or closure to or detaching the same from the bearing member or bolt.

With the above mentioned and other ends .45 in View, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in some of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to. the drawings, forming a part of this specification, Figure 1 is a 10ngitudinal sectionalview of the improved lubricator as applied to or embodied in an may j ordinary' spring or shacklebolt.

, Similarnumerals of reference designate ilike parts throughout all. the figures of the idrawings. The improved lubricator comprises a bear- ;mg or'pin member 1 consisting, in thepres fent embodiment, of a bearing or connecting ibolt' r for formingthe bearing or connection "Panamanian ra sin J Hey3,191$. 8erfla1Iil'o.:7,3..,-

between the spring or shackle members and Ethe sidebars or members of automobile vehicle frames.

' The hearing or bolt'member 1 is provided with a longitudinally extending bore or or receptacle 2-, said here or chamber- 2- extendingfrom oneend of the or bolt and. terminating near its: inner end in -an outlet slot" or opening 2?, the latter: comhearing or bolt member-1. I

as feedin through t e medium of'the plunger member .3 is detachabl mounted at one end' of the hearing or' hot member, said head-cap or closure being provided with a plungeract-uating stem 4 removably'mounted within and passing through the plunger or piston member 5 within the chamber or receptacle municating with 'alongitudinally extending lubricant distributing groove orchannel' 2") on. the exterior or bearing-portion. of tha- As a means fcr opening and closing the lubricant chamber or receptacle 2, as well I the lubricant from the latter hereinafter described, a head-cap or closure lubricant receiving and containing chamber :2. The inner end of the here or chamber I 2 preferably terminates in a bearing open- :ing 2 adapted to receive and contain the inner or bearing end 4 of the plurfgerlactuating stem, said bearing portion 4* beling preferably split to frictionally engage 'the bearing opening 2, as shown most clearly in Fig. 1 of the drawing.

As a means for causing the plunger memher 5 to be moved to and fro within the chamber or receptacle 2-by manual rotation 'of the head-cap 3 and plunger-stem 4:, the

latter is preferably threaded as shdwn in Figs; 1, 2 and 4, said threaded portlon'pa'ssing through an interiorly threaded opening or sleeve 5 of the plunger, the latter being preferably provided with circumferentially extending split wings -5 adapted to frictlonally engage within the walls of the chamber or receptacle 2 and prevent circumferential movement or rotation oftlie plunger"memher 5 as the rotated.

As a meansfor detachably mounting the head-cap or closure 3 in its closed or operative position, as well as resiliently holding chamber or receptacle 2, said circumferential groove Tbeing provided at suitable in- I tervals with notches or recesses 7 into which the free-ends of the spring member 6 are adaptedtofit or be seated to prevent accidental or undesirable circumferentlal movement, of the headscap, 3 andactuating stem 4 by jars, vibrations, or the like. v I

The spring member 6 may be formed from a single length or strip of material bent into loop form and detachably mounted in the head-cap 3, as shown in Figs. 1', 2, 4 and 5 of J the drawings, and as shown in Figs. 1 and 4-,

the spring members 6 are detachably mounted through the medium of an intermediate loop portion 6 mounted on a pin or cross member 8 extending between thumb wings 3 of the head-cap, and when it is desired to detach and remove the head-cap or closure 3 together with the plunger actuating stem 4 and plunger member 5 carried by the latter, the projecting portions and the spring member 6 may be pressed toward each other,

. 7 or recess 7.

videdwith a milled or If desired, the head-cap 3 may be proknurled head 3, as shown in Fig. 2 of the drawings, in which instance the head-cap is provided with a detachably mounted longitudinally movable U.- shaped member 8 held in and adapted to have a limited movement within the headcap by means of a retaining screw 8., the inner ends of the U-shaped member 8 being beveled and being adapted to coiiperate with the inclined or beveled portions 6 of the springs 6, it being obvious that an inward pressure of the U-shaped member 8' will move the spring members 6 toward each other, and thus release the latter from the groove 7 or recess 7.

In Fig. 3 of the drawings, I have shown a modified form of plunger comprising a plunger actuating stem 4 issaid threaded plunger, tachablysecuring said head-cap and normally preventing the circumferential movei ment of the same.

?ing in a double-walled plunger in which an inner member or cap 5 is provided, the split wings 5 of said inner member being arranged in overlapping or staggered relation to they outer win members 5 and terminatin in an outwardly extending flange 5" fitting or abutting against the ends of the outer wings 5", and extendlng riphery of said wings.

From the foregoing description, taken in connection with the accompanying drawings,-

terior communicating lubricator distributing groove, a threaded plunger provided with circumferentially extending split wings adapted to prevent rotation, a rotatable head-cap carrying a threaded stem adapted to rotate therewith and extending through and means for deflush with the outer pe- 2. In a lubricator bearing, a headed beari ing bolt provided with a cylindrical bore extending from said headed end and terminatbearing opening and a lubricant 1 outlet port, said headed end being provided with a circumferentialgroove' at the mouth of said bore, a threadedplunger member, a.

rotatable-head-cap. provided with a threaded stem extending through said threaded plun; ,ger and vhavingits innerend split and removably mounted in said bearing opening,

and a spring loop member having its free ends normally traversing said groove for detachably connecting saidrotatable head-cap to said bearing bolt and resiliently preventii-ng the rotation .of said headcap in the thereby detaching vor disengaging the free ends of the spring member 6 from the. groove latter. ,3. A lubricator,

said cylindrical bore a being tially extending groove having recesses, a

- threaded non-rotatable plunger member provided with split wings,a rotatable head-cap provided with a, fixed threaded stem extending through said threaded plunger member, and spring-memberscarried by said head- 4. In a lubricator bearing, a bearing bolt provided with a cylindrical bore terminating at its mouth in a circumferentially extending groove, the latter being provided at intervals with radially extending recesses, said bore terminating at its opposite or inner end in a bearing opening and a lubricant outlet port,

cap and adapted to interlock with and traverse said groove and recesses.

a threade plunger member, a rotatable head-cap qarrying a threaded stem extending throu h said threaded plunger and having its inn zsr end seated in said bearing opening, a pair of spring members carried by said head cap and adapted to traverse said groove ankl radially extending recesses.

Infesbimony whereof I have afiixed my slgnature in presence of two Witnesses.
